| 风机主轴是连接风机风翅与风机底座的重要部件，无锡风力风机制造有限公司风机主轴是中空的，风机主轴的材质是不锈钢的，内孔加工比较困难，现在对风机主轴的加工设备是深孔钻镗床，根据风机主轴的特性，深孔钻镗床要加高床头。 风力发电机的主轴既有径向偏移，又有轴向偏移。实际上，主轴的轴向偏移直接传递到齿轮箱的输入轴。除非对调心滚子轴承的径向游隙，轴向游隙控制以及行星轮的定位做特别处理，否则轴向的偏移会对齿轮箱里行星架支撑轴承产生不利的影响。主轴的轴向偏移取决于系统的刚性和固定端轴承的内部游隙。在固定端使用预紧的双列圆锥滚子轴承后，主轴右端的轴向偏移几乎比使用调心滚子轴承时减少4倍。减小轴向偏移可以减小轴向挤压齿轮箱输入轴的风险，这非常重要。（图/文http://www.wxfengli.com/） （中译英） Fan shaft is connected with fan fin and fan base of important parts, fan shaft is hollow, the fan spindle is made of stainless steel, inner hole processing more difficult, now on the fan shaft processing equipment is deep hole boring machine, according to the characteristics of the wind machine spindle deep hole boring, heightening the bedside. Main shaft of wind power generator with radial deviation, and the axial offset. In fact, the spindle is axially offset are passed directly to the input shaft of the gear box. Unless the self-aligning roller bearing radial clearance, axial clearance control and planetary wheel positioning for special treatment, or axial offset on the gear box planetary frame supporting bearing adverse impact. The spindle is axially offset depends on system of rigid and fixed end bearing internal clearance. In the fixed end use preload double row tapered roller bearing, spindle right end axial displacement than the use of spherical roller bearing is almost4 times less. Decreasing axial shift axial extrusion can reduce the input shaft of the gear box of the risk, this is very important. |
